Foot sweating may occur in kidney deficiency, but foot sweating is not necessarily a sign of kidney deficiency.
There are many reasons for foot sweating, such as dampness and heat in the spleen and stomach, dampness and heat in the liver and gallbladder, and kidney yin deficiency, etc. Sweating of the feet may also be caused by hot weather and breathable shoes and socks, which is generally normal. The cause of foot sweating needs to be judged in conjunction with other symptoms.
Foot sweating caused by kidney yin deficiency is often accompanied by symptoms such as five heart heat (heat in the hearts of the hands and feet, and self-consciousness of the heart and chest (irritability and sultriness)), lumbar and knee soreness and weakness, dizziness and tinnitus, insomnia and dreaming, spermatorrhea in men, and menstruation or amenorrhea in women.
If your feet sweat often, you should change your shoes and socks regularly and keep your feet dry.
If the symptoms of sweaty feet are not relieved for a long time or accompanied by other discomforts, it is recommended to consult a doctor in time to identify the cause and then carry out targeted treatment.
